Abstract

The invention discloses an accumulated snow depth calculation method and device, computer equipment and a readable storage medium, and is applied to the meteorological field, and the method comprises the steps that the computer equipment firstly obtains stationary satellite remote sensing data so as to obtain sensitive wave band data corresponding to accumulated snow, namely green wave band spectral data and short wave infrared band spectral data; then, according to a normalized snow accumulation index calculation formula and the green wave band spectral data and the short wave infrared wave band spectral data of each pixel, calculating a normalized snow accumulation index of each pixel, so as to calculate the snow accumulation depth according to the normalized snow accumulation index of each pixel in the subsequent process; and finally, based on a preset accumulated snow depth estimation model, calculating the accumulated snow depth of each pixel by using the normalized accumulated snow index of each pixel. Therefore, the accumulated snow depth is calculated by adopting the stationary satellite, so that the acquisition efficiency of the accumulated snow depth is improved.

Description

technical field [0001] The present invention relates to the field of meteorology, and in particular, to a method, device, computer equipment and readable storage medium for calculating snow depth. Background technique [0002] Snow depth is one of the indispensable parameters in snow cover research, such as snow water equivalent estimation, basin water balance and snowmelt runoff forecasting, and remote sensing monitoring of snow disasters in pastoral areas. Therefore, how to efficiently obtain snow depth is one of the current research hotspots. [0003] At present, the acquisition methods of snow depth include ground observation methods such as manual observation method and automatic observation method of snow depth field network. Among them, the manual observation method is the simplest ground measurement method, but it can only provide observation of snow conditions at a single time, and the measurement accuracy and temporal and spatial distribution in alpine regions are...

Problems solved by technology

Among them, the manual observation method is the simplest ground measurement method, but it can only provide observations of snow cover conditions at a single time, and the accuracy and temporal and spatial distribution of measurements in alpine regions are severely restricted

Although the automatic observation method of the snow depth field network improves the timeliness and accuracy of the measurement, it cannot meet the requirements of quickly extracting the snow depth in a large range due to the high price of the instrument and the influence of field weather and environment.
